It wont work because a program has no idea if it's running on h/w or s/w.
Everything a program may check can be faked. We don't do full emulation
much today because it's slow but with the Crusoe CPU you can fake any CPU ID
you like just by writing a bit of firmware/assembler to emulate all the x86
ID instructions.
